I've got one, haven't used it a lot. It is not as catch proof as the claim, but is pretty good. I've found that if I'm not careful I can make a groove much deeper than I planned. I'm still teaching myself how to use the various tools and find I prefer to use the traditional tools for making the various cuts even though I'm not very good with most of them, specially making beads with the skew. As such it spends most of the time on my tool rack. If you want I could send it too you to try out before you buy one. I'm sure I wouldn't miss it for awhile.
